you would normally catch with a subscript out of bounds error but
with the extra space it now runs without errors.

works.
You can build a matrix by building a vector one element at a time this way,
and then reshaping it at the end. That only works if you don't need it to be
a matrix at all times.
Another approach is to build a list of rows. It's not a ma
OK. I initialize real large vector and matrix and then shrink them when
I use them in the loop. The following lines worked. I'd glad to know of
better approaches.
bsum<-rep(0,1000); bsum
vsum<-matrix(rep(0,100),nrow=1000); vsum
for (ind in 1:3) { mydata <- read.csv(paste0("midata", ind, ".c
Is there as way to initialize a vector (matrix) with an unknown length
(dimension)? NULL does not seem to work. The lines below work with a
vector of length 4 and a matrix of 4 x 4. What if I do not know
initially the length/dimension of the vector/matrix?
All I want is to add up (accumulate)
